Aulis

Aulis, ancient Greek town in Boeotia, separated from Chalcis (on the island of Euboea) three miles to the north by the Euboean Channel. Aulis was traditionally held to be the port from which the Greek fleet set off to the siege of Troy and the scene of the related sacrifice of Iphigenia, the eldest daughter of Agamemnon, king of Mycenae.
